Answer:
x = 5
Step-by-step explanation:
0.5x + 3.5 = 6
0.5x = 6 - 3.5
0.5x = 2.5
x = 2.5 / 0.5
x = 5
Answer:
70cm2

Step-by-step explanation:
The frequency in a study like this means the number of people which chose that option. Since the patients must chose one of them, then the sum of all the frequencies must be equal to the number of patients that answered the research. With this in mind we can find the missing value, x.
There were 36 patients that reported no pain.
Answer:
56 pieces of candies at maximum.
Step-by-step explanation: What you want to do is just divide both numbers, giving you 56.2105263158. The decimals will give you the wrong answers, so taking them out, would be the best, and also the decimals aren't divisible to the 19 kids. When you take the decimals out, you should get 56. To prove my point, doing 56 x 19 = 1064 candies, and the 4 other is not able to be split to 19 kids. So there 56 is your answer!
Answer:
f(x) = sqrt(x + 6)
y = sqrt(x + 6)
x = sqrt(y + 6)
Stx^2 = y + 6
x^2 - 6 = y
red line: f(x) = sqrt(x + 6)
green line: f^-1(x) = x^2 - 6
